Dear Editor, Pitted keratolysis (PK), also known as keratosis plantaris sulcatum, is a non-inflammatory, bacterial, superficial cutaneous infection, characterized by many discrete superficial crateriform ''pits'' and erosions in the thickly keratinized skin of the weight-bearing regions of the soles of the feet (1). The disease often goes unnoticed by the patient, but when it is noticed it is because of the unbearable malodor and hyperhidrosis of the feet, which are socially unacceptable and cause great anxiety to many of the patients...

Worldwide melanoma incidence and mortality are increasing (1). Despite the ongoing research, advanced melanoma is still incurable; therefore, the most appropriate solution seems to be early detection combined with complete surgical excision (2). Since the diagnostic protocol of suspicious lesions includes a complete excision with safety margins (2), the problem of unnecessary scarring is significant. The real challenge in this case is to have a properly formulated diagnosis before acquiring a biopsy. Currently available non-invasive techniques are coherence tomography, digital dermoscopy, and reflectance confocal microscopy...

Purpose of Review: Reflectance confocal microscopy (RCM) enables imaging of skin lesions at cellular level resolution at the bedside (in vivo) or in freshly excised tissue (ex vivo). This article provides an overview of strengths and limitations of non-invasive RCM in skin cancer diagnosis. Recent Findings: RCM features of common melanocytic and non-melanocytic skin neoplasms such as melanoma, actinic keratosis/squamous cell carcinoma, basal cell carcinoma, and nevi have been well defined and show good correlation with dermoscopic and histopathologic findings...

BACKGROUND: Pityriasis rotunda is a rare skin disease characterized by the presence of multiple, round or oval, sharply demarcated hyperpigmented scaly patches. It has been described in Japan, South Africa, and in some other countries. The cause of pityriasis rotunda is usually idiopathic but may be associated with certain internal malignancy or systemic diseases. OBJECTIVE: The aim of this study is to describe this rare entity in Jordan in a retrospective study during the last 10 years...

Introduction: Lichen planopilaris (LPP) is a lymphocytic primary cicatricial alopecia presenting with scarring hair loss and variable degrees of perifollicular erythema and scaling. Pustules are infrequent and may mimic folliculitis decalvans (FD) and other forms of neutrophilic alopecia. We present a series of LPP cases with pustules and discuss the importance of differentiating them from primary neutrophilic folliculitis. Materials and Methods: Demographic, clinical, histopathological, and follow-up data of 13 cases of LPP with pustules followed at the Department of Dermatology of the University of São Paulo Medical School were described...

Extramammary Paget's Disease (EMPD) is a rare intraepithelial adenocarcinoma that classically manifests with pruritic, erythematous, scaling plaques. The clinical picture frequently mimics inflammatory or infectious conditions, and is thus commonly misdiagnosed. The assessment of tumor margins is equally challenging as tumors have a propensity to spread beyond clinically visible boundaries. Appropriate non-invasive diagnostic tools can assist in the early detection, diagnosis, and management of EMPD. This paper will review the literature on non-invasive imaging modalities used in EMPD...

BACKGROUND: Dermoscopy imaging has been a routine examination approach for skin lesion diagnosis. Accurate segmentation is the first step for automatic dermoscopy image assessment. OBJECTIVE: The main challenges for skin lesion segmentation are numerous variations in viewpoint and scale of skin lesion region. METHODS: To handle these challenges, we propose a novel skin lesion segmentation network via a very deep dense deconvolution network based on dermoscopic images...

Bowen disease with sebaceous differentiation has been rarely documented to date. Here, we present a case of Bowen disease with sebaceous differentiation. A 67-year-old man presented with a 6.0 × 3.5 cm erythematous plaque adjacent to a 7.0 × 3.0 cm erythematous plaque on his left abdomen. Dermoscopy revealed yellow structureless areas and dotted vessels on a pink homogenous background in addition to surface scales. Histopathological examination of the upper erythematous plaque showed parakeratosis and acanthosis with proliferation of atypical keratinocytes in the epidermis...

Background: With advances in medical imaging systems, digital dermoscopy has become one of the major imaging modalities in the analysis of skin lesions. Thus, automated segmentation or border detection has a great impact on the subsequent steps of skin cancer computer-aided diagnosis using demoscopy images. Since dermoscopy images suffer from artifacts such as shading and hair, there is a need for automated and robust artifact attenuation removal and lesion border detection. Methods: method for segmentation of dermoscopy images is proposed based on active contour...

BACKGROUND: Merkel cell carcinoma (MCC) is a rare, very aggressive tumour. The pathogenesis remains unclear, but UV radiation, immunosuppression, and the presence of Merkel cell polyomavirus in the tumour genome appear to have a key role. Merkel cell carcinoma is a highly aggressive tumour that often has a lethal end. CAS REPORT: A patient at 93 years of age comes for an examination by a dermatologist due to a rapidly growing nodular tumour growth in the forehead area...

we present the case of a 66 years-old male patient who presented a lesion on the left arm, appeared eight months before. The lesion was well circumscribed with a diameter of 15mm x 20mm and had the aspect of a hyperkeratotic scaly plaque, mildly pruritic. Dermoscopy showed structurless with pinkish area in the central area of the lesion and segmental brown radial lines at 1-3 o'clock, and a large scaly circular peripheral border with some linear vessel.

First described in 1965 by Mali et al., pseudo-Kaposi sarcoma (PKS), also known as acroangiodermatitis, is a rare disease inscribed in the setting of cutaneous reactive angiomatoses (CRAs). CRA are all characterized by occlusion and/or inflammation of cutaneous vessels, followed by histiocyte recruitment and endotheliocyte and pericyte hyperplasia. As the name suggests, PKS nearly resembles Kaposi sarcoma, but is benign in its nature. PKS typically presents with violaceous papules and plaques, usually located on the inferior limbs...

An early diagnosis is of overwhelming importance for the management and prognosis of mucocutaneous cancer. Actinic cheilitis (AC), defined by the clonal expansion of genomically unstable keratinocytes, is the most common potentially malignant lesion affecting the lips. Squamous cell carcinoma (SCC) is the most frequent oral malignancy, and there is strong evidence that the majority of the SCCs of the lip originate from AC. There is considerable difficulty in discerning between dysplasia and invasive carcinomas solely on a clinical basis...

Inflammatory breast cancer is an aggressive and infiltrative malignancy that is often misdiagnosed as an infection because of its symptoms and signs of inflammation, delaying proper diagnosis and treatment. We report a case of inflammatory breast cancer showing correlation between dermoscopic and histopathological diagnoses. We highlight the utility of dermoscopy for skin biopsy site selection.

Terra firma-forme dermatosis (TFFD) is an acquired benign disorder that is characterized by brown-gray patches or plaques, presenting as dirt-like pigmented areas (1, 2). The diagnosis is usually confirmed by the clearing with isopropyl or 70% ethyl alcohol swab, that is also the gold standard of treatment. Dermoscopy of TFFD may show large polygonal plate-like brown scales arranged together giving a mosaic or cobblestone pattern (3) This article is protected by copyright. All rights reserved.

BACKGROUND: Under dermoscopy, discoid lupus erythematosus (DLE) exhibits specific findings. Commonly DLE lesions affect sun-exposed sites, especially the face. However, most of the dermoscopic reports come from scalp DLE. To our knowledge, the dermoscopic pattern for mucosal and labial DLE has not been previously reported. METHODS: This study included 20 patients with histopathologically confirmed DLE lesions. Full history taking was obtained with photo documentation of lesions including the sites involved, the number of lesions per site, and the total number of lesions affecting every patient...
